Not to de-rail the thread but since stereo audio is mentioned, is anybody here a fan of binaural audio? There were some binaural demo albums released long ago, and a decade or two ago some fantastic binaural audio dramas were released on cassette and CD.

The three Star Trek: Captain Sulu audio adventures from Simon & Schuster were released in binaural audio CD in 1994-95. They are available on iTunes (and maybe Audible) now - there are some cool effects, especially in bridge scenes - you get a sense of which actor is at which station, relative to the captain's chair.

Most recently, on the Doctor Who: Complete Series 10 blu-ray, which came out in November 2017, the fourth episode - "Knock, Knock" - about college students going missing in a haunted house - also included an optional binaural audio track for that episode only. All the episodes have 5.1 tracks as well. If the binaural track is selected, a warning screen comes up advising the viewer to use this option with headphones only. It has some great creepy creaky effects.

Has Bob indicated whether they were able to save the stereo soundtrack?

Almost all of the 1950's 3D titles stereo soundtracks are lost. 3D Film Archive has Eckhard BŁttner restoring the three-channel stereophonic sound from other sources. All of the ones he has done in the past sound fantastic! The major studios should hire Eckhard BŁttner to restore all their mono tracks for titles where the stereo track are lost.

Indeed. but I'd still like an alternate stereo track, my TV doesn't like three channel audio.

Nevertheless, this will be an amazing 3D release I'm not going to hesitate to pre-order, another good reason for Region B folks to get Region A compatible, because you ain't going to see this stuff any other way... well, not legitimately anyway...

3D is not dead. What's dead is my interest in any new 2D formats or display technology.
